IMPROVED DEVICE FOR MARKING CORN-FURROWS.

Specification forming part of Letters Patent No. 33,478, dated October 15, 1861.

To all 107mm 1' t may cqncem:

Be it known that I, GEORGE G. GRosE, of Schoolcraft, in the county of Kalamazoo and State of Michigan, have inventeda new and Improved Machine for Marking and Farrowing for the Planting of Corn; and Ido hereby declare that the following is a full, clear, and exact descriptionot' the same, reference being had to theannexed drawings, making a part of this specification, in which- Figure 1 is a plan or top view of my invention; Fig. 2, a front view of the same in an unfolded state; Fig. 3, a perspective view of the same in a folded state; Fig. 4, a front view of the same in a partially-folded state.

Similar letters of reference indicate corresponding parts in the several figures.

To enable those skilled in the art to fully understand and construct my invention, lwill proceed to describe it. i

A represents what may be termed a sled, the same being composed of two runners, a a, connected at their upper edges by ties b b, and having a bar, 0, fitted in their lront ends, to which a draft-pole, B, is attached. The bar 0 is provided with a tenon or journal, (1, at each end, and these journals are allowed to turn freely in the runners at a, so as to admit of a proper vertical play of the draft-pole.

To the front edge of the front tie b of the sled A there is secured a metal bar, 6, and a similar bar, 6, is secured to the back edge of the back cross-tie I). These bars 6 6 project a short distance beyond the ends of the crossties, and between them, at each side of the sled, planks O O are secured by rods D, said rods also passing through metal bars ff at the sides of the planks O (l, and forming-joints or hinges, as shown clearly in Fig. 1.

To the outer ends of. the planks O O run- These runners E are precisely similar to the runners at a. To the outer ends of the planks O (3 similar planks, D l), are attached by hinges E E, and to the outer ends of the planksU O runners g g are secured, said runners being precisely like the others previously described. The runners a a E E g g are placed at equal distances apart, the distance being equal to the width desired between the rows of corn.

The operation is as follows: If the machine is fully unfolded,-as shown in Figs. 1 and 2, six furrows will be made at once, and each part A CD of the machine will be allowed to rise and fall to suit the inequalities of the surface of the ground, in consequence of said parts being connected together by hinges. This is an important feature of the invention, for it insures the ground being, thoroughly marked-the elevations as well as the depressions. In case it is desired to make only four furrows at a time, the outer parts, I) D, are turned up or folded on the parts 0 O, as shown in Fig. 4. In case it is desired to form only two furrows, the parts O U are turned up, as shown in Fig. 3. It will be seen that this hinging of the parts together enables any part to be raised to pass over obstructions, and in passing through gates or bars the machine may be readily folded or contracted, so as to form a comparatively narrow affair and admit ofits passing through a quite narrow place. The implement may be quite cheaply constructed and with a few ordinary tools. When desired, allof the markers may be turned over, so as not to operate on one side of the machine, and all of the markers except one on the other side, and thus three furrows will be marked. Four, five, or six furrows may be marked, as desired, by adjusting the markers.

I am aware that hinged markers are not new, and I do not claim them broadly as my invention; but,

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The arrangement, with the runners aa and ties b, of the hinged planks O O D 1) and runners E E g g, as herein shown and described, so that two, three, four, five, or six furrows may be made, as desired, all as set forth.
